? 2021 Elsevier Masson SASObjective: Multiple conventional transarterial chemoembolization (cTACE) procedures would cause treatment resistance in hepatocellular carcinoma (HCC) patients, whether drug-eluting bead transarterial chemoembolization (DEB-TACE) would resolve this issue is a necessary topic. Thus, this study aimed to compare the efficacy and safety between DEB-TACE and cTACE in HCC patients with cTACE treatment history. Methods: Totally, 134 HCC patients with cTACE treatment history were retrospectively reviewed. They were categorized into DEB-TACE group (N = 70) and cTACE group (N = 64) based on the current treatment they received. Results: After 1-month treatment, DEB-TACE group exhibited an elevated objective response rate (ORR) (71.9 vs. 47.3, P = 0.008) while similar disease control rate (DCR) (93.0 vs. 81.8, P = 0.074) compared to cTACE group. Besides, after 3-month treatment, DEB-TACE group also displayed higher ORR (68.4 vs. 44.1, P = 0.038) and DCR (81.6 vs. 58.8, P = 0.034) compared to cTACE group. Furthermore, the median progression-free survival (PFS) (11.5 months vs. 6.5 months P = 0.014) and overall survival (OS) (18.5 months vs. 13.0 months, P = 0.025) were longer in DEB-TACE group compared to cTACE group. Moreover, DEB-TACE (vs. cTACE) independently correlated with prolonged PFS (P = 0.021) and OS (P = 0.017) after adjustment by multivariate Cox's regression. Besides, most of liver function indexes were similar before and after treatment between these two groups. Also, the commonly observed adverse events were pain, fever, nausea/vomiting and blood pressure elevation with similar incidence between these two groups (all P > 0.050). Conclusion: DEB-TACE exhibits superiority over cTACE in HCC patients with cTACE treatment history.
